driver/tool.cpp

[Joseph Rushton Wakeling via digitalmars-d-ldc]

Weird issue after pulling in latest LDC git master.

git is reporting that driver/tool.cpp has been changed.  The 
checkout and reset commands don't alter this.  git difftool -t 
meld reports that the file is actually unchanged (!).

Anyone have any clue what's behind this?  I ran git submodule 
update but I don't think this is submodule code ... ?

Thanks & best wishes,
